Dart VM improves performance by 50%

The Dart VM is now 50% faster than Chrome’s JavaScript engine, V8, on the two Octane benchmarks, Richards and DeltaBlue.

This info is available and being tracked on dartlang.org/performance/, which we’ve launched today. It is the new place for up-to-date information on Dart performance. We’re tracking and comparing performance of V8, the Dart VM, and the Dart to JavaScript compiler for every new revision, so you can now follow performance improvements as they are landing and help us keep an eye out for regressions.

The benchmarks are run on a Linux ia32 architecture and follow the standard Dart benchmark harness. Over time, we'll add to the set of benchmarks being tracked. Of course, benchmarking is a subtle science, which is why we've published a short guide on benchmarking Dart. It's still early for Dart VM, but we're encouraged by the initial performance boost for web developers. If you are too, download the Dart SDK and get started today. We encourage you to send feedback using our mailing list.
